I've had the BT-7 for my third day now but I'm handing it off to my son in the morning. I can only describe it as WOW!!!!
The combination of a tuned head, two dropperfulls of SSKI 2%, various co-factors, and a bowl of sour diesel hydo make for a very dangerous man. I fear this, yet I'm as calm as a clear water pool deep inside the stillness of a cave.
I highly suggest the BT-7 as a must have for EVERYBODY
